SPECIFICATION forming part of Letters Patent No. 509,853, dated November 28, 1893.

T a/ZZ whom it may concern.-

Be it known that I, OTTO EISELE, machinist, a subject of the Emperor of Germany, and a resident ot' Carlsruhe, in the Grand Duchy of Baden, German Empire,have invented eertain new and useful Improvements in Casement-Holders, (for which I have obtain ed Letters Patent in Germany, No. 66,253, dated March 26, 1892,) of which the following is a ro specification.

My invention has reference to improvements in holders for easements, hinged sashes, doors, transoms and the like, and has for its objects to provide simple and effective means whereby the easement may be held at any desired angle, and at the same time prevented from being opened or closed too rapidly.

With these objects in view my invention consists essentially in a easement holder comzo prising two spring pressed blades provided with recesses, and pivoted to swing toward and from each other, and a pin secured to the caseinent and arranged to project between said blades;-all of which is hereinafter more fully z 5 pointed out, reference being had to the accompanying drawings in which- Figure l represents a plan view of a device constructed according to my invention, the blades being shown closed. Fig. 2 is a face 3o View of one of the blades detached. Fig. 3 is a plan view showing the blades open. Fig. 4 is a detail View ot the eye bolt for attaching the device to the framing. Fig. 5 is a sectional side View showing the device applied.

3 5 `Similar letters of reference designate corresponding parts throughout the several views of the drawings. y

In the drawings, the letters c c designate two metallic blades provided each with a se- 4o ries of recesses h taperingor flaring outwardly. The blades are pivoted adjoining one another in the manner of the blades of a pair of seissors, that is to say, one is located directly below the other to permit the blades to swing past each other. The recesses are arranged opposite to each other. The blade c is formed with a square socket adapted to t the square portion of a pintleawhile the blade c isbored out sufficiently to turn about the said pintle.

5o One end of a spring e, coiled about and secured to the pintle, is extended and arranged to engage the outer side of a pin d securedin the blade c, whereby the two blades are forced toward each other. The pintle a. is mounted in a suitable eye bolt f attached to either the lower or upper horizontal portion of the easement framing.

To the easement is seeureda pin g located in a position to project between the two blades e c (Figs. 3 and 5). The pintleoof the blades 6o can turn in its bearings in the eye bolt f, so that the blades c c will accommodate themselves to the are described by the pin gin the easement when the latter is opened and closed. Assuming the easement to be closed and that it is turned about its hinges to open, the pin g forces the blades e c' apart against the aetion of spring c as said pin emerges from the first recesses h h. On continued motion of the easement the pin is again brought oppo- 7o site to two of the recesses and the blades again close; then they are again opened (Fig. 3) and so on, the pin successively entering the several recesses. The sash is therefore automatically held in the position of its release.

Furthermore it will be noticed that the force necessary to open the blades as the pin leaves the recesses acts as a check to the too rapid opening or closing of the easement. j

According to the dimensions of the case- 8o ment the taper of the recesses may be made more or less wide, so as to insure the retention of the easement with certainty againstits own weight when swung about a horizontal axis, as well as against the force of the wind.

To reduce the motion of the blades to a minimum the inner edges of the same may be made taper.

It is evident that one blade may be made without recesses; also that the blades may be 9o made curved to correspond to the are in which the pin g swings; and also that one ot' the blades may be stationary; in which latter case both blades must be curved.

What I claim as new, and desire to secure by Letters Patent, is

l. A easement holder consisting ot two blades pivoted to swing the one toward the other and provided with recesses, a spring for 'pressing the blades together, and a pin on the roo easement projecting between the blades, substantially as described.

2. A easement holder consisting of two In testimony that I claim the foregoing as blades provided with taper recesses' and pivmyinvehtion I have signed my name in presoted to swing toward and from each other and ence of two subscribing Witnesses. with their comnon pivot, a springfor forcing OTTO EISELE.
